Abstract
The utility model discloses a comb-tooth-shaped and ladder-shaped vibrating screen which comprises a screen frame (1) and screen boards (2). The comb-tooth-shaped and ladder-shaped vibrating screen is characterized in that the screen boards (2) are arranged on the screen frame (1) in a ladder-shaped mode and form certain angles with the screen frame (1); and screen faces (3) of the screen boards (2) are composed of a plurality of screen bars (4) which are arranged in a parallel mode. Due to the combination of a comb-tooth-shaped structure and a ladder-shaped structure, screening of humid stickiness materials with sizes less than 6 millimeters is easily achieved, and minimum screening size is 2 millimeters.
Description
Technical field
The utility model relates to a kind of vibratory sieve, relates in particular to a kind of comb teeth shape ladder vibratory sieve.
Background technology
Compass screen surface is one of main working parts of vibratory sieve, to the basic demand of compass screen surface is: enough intensity be arranged, and the maximum percent opening ratio of whole cover surface (the sieve aperture gross area with) and sieve aperture are difficult for stopping up.The compass screen surface kind is a lot, and since the self-excited oscillation sieve came out, people had invented various compass screen surfaces to adapt to the screening operation of different material.But the small particles material that viscosity is bigger is whole operation forward at compass screen surface through moisture, laxity is very poor, so existing material dry screening is for the screening of moist viscous material below the 6mm, be difficult to carry out, and wanting to make material normally to sieve, the material group must and sieve three processes thoroughly through loose, layering.If the material group can not be loose, next step just can not layering, can not layering, and small particles material just can not contact compass screen surface, just can not sieve thoroughly.Therefore, the screening for moist viscous material below the 6mm needs a kind of novel vibratory sieve to finish screening.
Summary of the invention
For solving deficiency of the prior art, the utility model purpose is to provide a kind of comb teeth shape ladder vibratory sieve.
The utility model is for achieving the above object, and the technological means that adopts is: a kind of comb teeth shape ladder vibratory sieve, comprise screen frame, sieve plate, and described sieve plate is installed on the screen frame with staged, and angled with screen frame; The compass screen surface of described sieve plate is arranged in parallel by many gratings and forms.
Further, an end of described grating is fixed on the sieve plate framework other end cantilever by the polyurethane casting.
Further, described sieve plate and screen frame angulation are 15 °～30 °.
The utility model beneficial effect is: by broach and two kinds of textural associations of ladder, make the screening of the following moist viscous material of 6mm easily finish, minimum step sizing has been accomplished 2mm.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Among the figure: 1, screen frame, 2, sieve plate, 3, compass screen surface, 4, grating.
The specific embodiment
A kind of comb teeth shape ladder vibratory sieve as shown in Figure 1 comprises screen frame 1, sieve plate 2, and described sieve plate 2 is installed on the screen frame 1 with staged, and angled with screen frame 1; The compass screen surface 3 of described sieve plate 2 is arranged in parallel by many gratings 4 and forms.
Further, an end of described grating 4 is fixed on sieve plate 2 frameworks other end cantilever by the polyurethane casting.Described grating 4 is evenly distributed by the 60Si2Mn spring lever of diameter phi 2.5mm-φ 8mm.
Further, described sieve plate 2 is 15 °～30 ° with screen frame 1 angulation.
2 pieces of sieve plate are installed on the screen frame 1 of strong vibrating screen, and when the material group passed through grating 4, under big oscillation intensity effect, grating 4 made material loosening because elasticity can swing up and down, and is difficult for being bonded on the grating.When simultaneously the material end that runs to every row's grating was fallen on next ladder grating, chien shih material group fractures in a moment, and was loose.Material during grating, all will repeat said process through each row, thereby makes constantly loose, layering of material group, saturating sieve; Enter sieve down less than the saturating sieve of the particle of sieve seam, drain from compass screen surface greater than the particle of sieve seam, screening efficiency is higher, and sieve seam minimum can be accomplished not plug-hole of 2mm.
The above; be the specific embodiment of the present utility model only, be not limited thereto, anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection domain of the present utility model.
Claims (3)
1. a comb teeth shape ladder vibratory sieve comprises screen frame (1), sieve plate (2), it is characterized in that: described sieve plate (2) is installed on the screen frame (1) with staged, and angled with screen frame (1); The compass screen surface (3) of described sieve plate (2) is arranged in parallel by many gratings (4) and forms.
2. comb teeth shape ladder vibratory sieve according to claim 1 is characterized in that: an end of described grating (4) is fixed on sieve plate (2) framework other end cantilever by the polyurethane casting.
